In'the' presentinstancgfithe inner face ct-the, hiib 11 cf the sprocket is provided; with a plurality of radial grooves 12 which are adapt.- ed" for the reception. of. aQpi'n- 13 rejecting radially fromthe shaftfwherebjy t esprocket 11 isprev' enfted normally from rotatingin: dependently of the shaft. Asliitable head 14 is-provided on: the and of the. shaft and acts a s -an abutment for'one end of aisprin'g 15 whose other end bears. against. "the. outer tac'ei of the :sprocket and tends. tfo holdjthe sprocketagainstthe. pin 'It will be-=a;p -v parent that by. forcing. the. sprocket outwardly-against the spring, the Tsprocketymay be released from the-pin 13 so that it ma be adjusted rotationallyv uponthe shaft.

Upon the opposite end of theishaft '4 isa pulley =wheel16 whichisconnected by means qf -a belt 117' with a. similar pulley :1'8,i1pon.a shaft-19- moun'ted in suitahle. beari@s-[21, 21, at the ibottgmea ndlrear of'the casing, these bearings 21 being adjustably secured to the casing'by means in each case of a bolt 22 which extends through the casing and through a horizontal slot ..3 in the bearin bracket. lVith this arrangement, it will be apparent that these hearings may be adjusted laterally with the shaft 19 which they carry, horizontal slots 2t corresponding to the slots 23 being provided in the side walls of the casing for passage therethrough of the shaft 19.

Secured to the shaft 19 intermediate the side walls of the casing by means in the present instance of set screws 25, 25, are a pair of sleeves 26, 26, said sleeves confining therebetween an apertured disk 27 having projecting upwardly therefrom a pin 28 which is adapted to lit within the lower recessed end of a rod 29 and thereby to anchor the said lower end of the rod in a given position relative to the shaft 19, as best illustrated in Fig. 7. This rod 29 extends upwardly through the casing at the back and is confined at the top between a pair of lugs 31, 31. which latter occupy recesses 32, 32, in the sides of the rod, as best illustrated in Fig. 5, a pin being passed through apertures in the outer ends of the lugs 31, and providing means for detachably securing the upper end of the rod between the lugs.

Secured to the inner face of one of the sleeves 26 by set screws 35 is a cutter disk 34, said disk being in the present instance toothed, as clearly illustrated in Fig. 7, and thereby constituting in effect a rotary saw, the teeth projecting a slight and predeter mine-d distance beyond the surface of the sleeve 26, to which the disk is attached.

By reference to Figure 8, it will be noted that the pin 28 is offset laterally with respect to the disk 27 to which it is attached whereby the cutter disk 3% is permitted to assume a position substantially directly in line with the center of the said pin and of the rod 29. The rod 29 constitutes a securing and guiding means for the articles which are to be fed from the device, which articles in the present instance are shown in the form of flat sheets or .slips of paper 36, each of these slips being provided at its rear end with an aperture through which the rod 2; passes, the slips being passed onto the rod by releasing the upper end of the latter and sliding it forwardly from between the supporting lugs 31. The rod 29, together with a stirrup-shaped member 37 which is adapted to occupy a position in the interior of the casing, constitutes the magazine for the slips 36, the stirrup 37being supported in the casing in an upright position at each side between a lug 38 projecting inwardly from the side wall of the casing and the inner end of an adjustable bolt 39 which projects through the side wall of the casin best illustrated in Figs. 2 and 8.

Each of the upright portions of the stirrup 37 is provided on that edge abutting the bolt 39 with a slotted recess 11 which is shaped to conform to the inwardly projecting end of the bolt 39 whereby when the stirrup is elevated, the said bolts 39 or the inner ends of said bolts may pass into the slots i1 and thereby support the stirrup in an elevated position. To assist in the elevation of the stirrup and to also constitute a means for supporting the stirrup in the lower operative position, each of the up. right portions is provided at the top with an outwardly projecting arm or shoulde: 42 which overlies the sides of the casing, best illustrated in Fig. 3. Each side wall of the casing is also provided near the bottom with a pair of lugs 4-3, t3. which at the bottoms are spaced a distance apart (302" responding to the width of the lower end of the stirrup 37, the lugs diverging towards; the top, as illustrated in Figs. 1 and 2. The lower end of the stirrup lies between these pairs of lugs whereby the lugs are made to constitute guides for the stirrup, insuring a proper positioning of the lower end of the latter approximately across the center of the paper slips and in proper position to support the slips in the magazine.

The operation of the device is as follows:

The magazine being provided with the slips or other articles which it is desired to dellVBl'. operation of the shaft r efl'ects rotation of the feed roller 5 upon which the forward end of the lowermost. slip 36 rests. as best illustrated in Fig. 2. When the frictional area 7 comes in contact with the lowermost of the slips 36, this slip is carried forwardly and passed through the opening 2. During rotation of the shaft -1, by means of the pulleys 16 and 18 and the belt 17, the shaft 19 is also rotating and with it the cutter 34. The teeth of the out ter, as previously described, project beyond the surface of the sleeve 26 to which it is attached a predetermined extent, which in the present instance is approximately the thickness of one of the slips 36. As the cutter blade is rotated therefore and by reason of the position of the cutter blade with respect to the lower end of the rod 29. as best illustrated in Figs. 2 and 7, the cutter operates upon that portion of the paper immediately to the rear of the aperture through which the rod extends and severs the paper between this aperture and the rear edge of the slip. By reason of this cutting action, the slip is permitted under the action of the roller 5 to slip easily forward from underneath the other slips in the magazine. there being nothing except the flitftlOllili contact between the bottom slip and those above it and the smooth upper face of the horizontal portion of the stirrup upon which the slips rest to prevent detachment of the slip. By reason of the correspondence between the thickness of theslips and-the exposed portion of tliecutter blade, it will be apparent that the cutter is permitted to sever but one slip at a time, thereby insuring a proper operation of. the mechanism and the retention of the slips in their. normal positions until individually acted upon by the frictional portion 7 of the feed roller 5. An exact adjustment ofthe cutter element 34 istprovided by means of the aforedescribed means for adjusting the bearings 21 of the shaft 19. To refill the magazine, the stirrup 37 may be elevated andthe rod29 released as previously described. without stopping the workingparts; oradditional slips may be added to those already in the magazine by merely releasing the rod 29. and without elevating the stirrup, in which case the feeding is uninterrupted. Obviously to interrupt the feeding without stopping the 1neclianism,.it is only. necessary to elevate the stirrup.

\Vhere the device is operated in connec tion with a machine such as the aforesaid wrapping machine, it is usually found desirable to operate the device directly from the mechanism of the machine with which it is used. Under these circumstances, it is necessary to synchronize the two mechanisms so that the articles are fed at correct intervals in the operation of the main machine. This synchronization may be eifected without disturbing the connection between the machinesby adjusting the sprocket 9, as previously described.
